Definitions
- Bisphenol A (2,2-bis(4-hydroxyphenyl)propane) is commercially prepared by condensing 2 moles of phenol with a mole of acetone in the presence of an acid catalyst. The phenol is present in a molar excess of the stoichiometric requirement.
- the purification of bisphenol A is a costly multi-step procedure entailing distillations, crystallizations, solvent extractions, evaporations and like procedures.
- a mother liquor is obtained.
- the mother liquor after distillation, forms a mother liquor residue which contains lower boiling reaction by-products, bisphenol A and higher boiling reaction by-products to name a few components.
- This mother liquor residue is a tarry residue which still contains valuable, recoverable materials.
- Figure 1 is a schematic representation of an embodiment described herein.
- bisphenol A is made by the condensation of 2 moles of a phenol with 1 mole of acetone in the presence of an acid catalyst. Phenol is used in excess of the stoichiometric requirements. Exemplary processes are described in U.S. Patents
- reaction zone effluent is continuously withdrawn and cooled to precipitate crystalline 1:1 adduct of bisphenol A and phenol.
- the solid adduct is filtered out, leaving a mother liquor.
- the mother liquor comprises bisphenol A, phenol and by-products.
- the mother liquor is treated to recover useful components such as phenol and bisphenol A.
- the mother liquor can be heated, typically to a temperature of 55°C to 95°C, to promote isomerization of related isomers of bisphenol A to bisphenol A (2,2-bis(4-hydroxyphenyl)propane) prior to distillation.
- the mother liquor may, alternatively or additionally, be treated with ion-exchange resins and/or filtered.
- the mother liquor is distilled to remove bisphenol A, phenol, solvents, and other useful materials. After distillation, the remaining tarry residue is the mother liquor residue.
- Exemplary distillation techniques include progressively (sequentially) higher vacuum/temperature conditions in order to separate the mother liquor into four fractions.
- a first distillation column is operated under vacuum and temperature conditions to remove an overhead fraction containing relatively pure phenol (e.g. >97 purity).
- the bottoms of the first column are fed to a second distillation column.
- This second column operates under reduced pressures and elevated temperature conditions which remove a colored "light" fraction consisting mainly of residual isomers of bisphenol-A and Chroman along with other byproducts with known and unknown chemical structure. This lights fraction can be purged and discarded, or subjected to additional recovery by this or other processes.
- the bottoms of the second column are fed to a third column.
- the overheads of this third column typically contain 60-90% pure bisphenol-A depending on the temperature and pressure conditions used.
- the bottoms of the third column contain "heavies" or tars which is the mother liquor residue used in the recovery method described herein.
- Aromatic sulfonic acids may be represented by the general formula RC 6 H 4 SO 3 H in which R may be in any position in the phenyl ring wherein R represents hydrocarbyl having 1 to 25 carbon atoms, inclusive.
- Exemplary aromatic sulfonic acids include p-toluenesulfonic acid and dodecylbenzene sulfonic acid
- hydrocarbyl as used herein means the monovalent moiety obtained upon removal of a hydrogen atom from a parent hydrocarbon.
- Representative of hydrocarbyl is alkyl of 1 to 25 carbon atoms, inclusive, such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, undecyl, clecyl, dodecyl, octadecyl, nonodecyl, eicosyl, heneicysyl, docosyl, tncosyl, tetracosyl, pentacosyl and the isomeric forms thereof; aryl of 6 to 25 carbon atoms, inclusive, such as a phenyl, tolyl, xylyl, napthyl, biphenyl, tetraphenyl and the like; aralkyl of 7 to 25 carbon atoms, inclusive,
- the aromatic sulfonic acid is present in amounts of 100 to 10,000 parts per million by weight (ppm) of mother liquor residue, more specifically, 1000 to 5000 ppm, more specifically 2100 to 2700 ppm, even more specifically 2300 to 2550 ppm.
- Cracking occurs at temperatures of 100°C to 300°C, more specifically, 120°C to 180°C, and even more specifically 135 °C to 165 °C. Cracking can occur at a pressure of 150 to 250 millimeters (mm) Hg, more specifically, 175 to 225 mm Hg.
- the cracker tank/heat exchanger may contain one or more internal baffles and one or more overflow baffles.
- Mercaptans are sometimes used a co-promoters in bisphenol A synthesis. Distillation can occur in a distillation column which is located after the cracker tank/heat exchanger.
- FIG. 1 An exemplary method is shown in Figure 1 where stream 5 is the mother liquor, 104 is a mother liquor tank, 43 and 46 are distillation steps, 33 is a condenser (also referred to as a phenol receiver) and C is where the cracking step occurs.
- Stream 5 is a mother liquor which can comprise 75 to 85 weight percent phenol, 10 to 15 weight percent of a combination comprising bisphenol A, isomers of bisphenol A and other byproduct components.
- Stream 1 is the mother liquor residue that can comprise 70 to 80 weight percent bisphenol A and isomers of bisphenol A, 0.5 to 3 weight percent phenol, with the balance being other byproduct components.
- Stream 2 is a tarry mixture that can exhibit viscosities of 80 to 230 centipoise at 176 "Celsius.
- a mother liquor comprising 80 weight percent phenol, 14.5 weight percent bisphenol A and bisphenol A isomers with the balance comprising other by-products feeds into a phenol distillation column that is equipped with Mellapak 125X in the top section and Mellapak 252Y in the bottom section as packing material.
- a phenol distillation column that is equipped with Mellapak 125X in the top section and Mellapak 252Y in the bottom section as packing material.
- This column may operate with an overhead pressure of 100 to 150 mm Hg.
- the overheads stream enters a condenser and into a phenol receiver.
- the effluent stream from the phenol receiver is mainly pure phenol (-99%).
- a cracker is present at the bottom of the column.
- the cracker may comprise one or more internal baffles and one or more overflow baffles and can operate at 120 to 180 °C, more specifically 135 to 165°C, and an outlet stream pressure of 150 to 250 mm Hg, more specifically 175 to 225 mm Hg. Greater than or equal to 50 weight percent of the total feed to the cracker can be converted to phenol.
- the bottoms stream of the secondary phenol stripping column is tar to burn.
- the secondary phenol stripping column can be a packed one comprising Koch type packing.
- the temperature along the column's axial direction can be 120 to 180 °C.
- Embodiment 1 A process for recovery of materials from a mother liquor residue comprising cracking a mother liquor residue with an aromatic sulfonic acid catalyst to form a cracked product mixture and separating phenol from the cracked product mixture wherein the mother liquor residue results from distillation of a mother liquor resulting from bisphenol A synthesis and isolation.
